function Randrange (data) {
    var newtime = Data[math.floor (Data.length * Math.random ())];
    return newtime;
}
function togglesomething () {
    var timearray = new Array (MB, m, MB, N, 3000, 1000, 1500);
    Do stuff, happens to use jQuery here (nothing else does)
    $ ("#box"). Toggleclass ("visible");
    Clearinterval (timer);
    Timer = setinterval (togglesomething, Randrange (Timearray));
}
var timer = setinterval (togglesomething, 1000);
1000 = Initial Timer When the "page is" a loaded
